Although he hasn't been stung, she is concerned about the auto-injector he carries. The mother states that it was prescribed when her son was 13 years old. She shows you the 0.15 mg auto-injector, and you note that it expired about 12 months ago. Which of the following statements would be most appropriate for you to make?

b. If you go to the pharmacy where you got this they will be able to give you a new one.
